Quick TakeThis watch is a pure celebration of the beautiful complexity ticking away inside. It’s as if Hamilton decided that hiding the magic of the H-10 automatic movement was a crime, and frankly, they were right. That warm apricot dial is the perfect stage for the main event: the open-heart display. You get a front-row seat to the constant, hypnotic dance of the balance wheel, a visual reminder that you're wearing a piece of living machinery. It’s got an incredible 80-hour power reserve, meaning this beauty can be set down on Friday and will still be perfectly on time come Monday morning. The 36mm stainless steel case feels solid yet graceful, and the bracelet is pure comfort. It’s a statement piece for the woman who finds beauty in engineering and isn't afraid to show off the brilliant inner workings that make her tick. It’s confident, mechanically fascinating, and utterly captivating.

DescriptionThe Hamilton Jazzmaster Open Heart Lady Auto, designated by reference number H32215100, is constructed with a stainless steel case that measures 36mm in diameter and has a thickness of 10mm. This case architecture ensures water resistance to a pressure of 5 bar, which corresponds to a depth of 50 meters or 73 psi. An open case back is incorporated for a view of the movement from the rear. Protecting the dial is a sapphire crystal treated with an anti-reflective coating to maximize clarity and reduce glare. The timepiece is affixed to a stainless steel bracelet (strap reference H6053241051) which integrates into the case via an 18mm lug width. This bracelet utilizes the Easy Click system for tool-free removal and is fastened by a butterfly buckle with a width of 16mm.

Powering the watch is the Caliber H-10, an automatic three-hand movement. A significant attribute of this caliber is its extended 80-hour power reserve, allowing for more than three days of continuous operation without winding. The movement incorporates a Nivachron balance spring, a material known for its superior resistance to magnetism, temperature fluctuations, and shocks, which contributes to the watch's overall timekeeping precision and reliability. The apricot-colored dial is distinguished by its open-heart design, featuring strategic cutouts that reveal the intricate, rhythmic motion of the balance wheel and escapement. These visible components showcase the snail and pearled patterns characteristic of the H-10 movement used in the American Classic series.
